Free tools to help you build the perfect home entertainment space.
TheaterCalc was created to solve a common problem: figuring out the right equipment for your space shouldn't require an engineering degree or hours of research across dozens of forums and spec sheets.
We build free, easy-to-use calculators that take your room dimensions and preferences, then provide clear recommendations backed by industry standards from SMPTE, THX, Dolby, and other audio-visual authorities.
Calculate throw distance, screen size, and brightness requirements based on your room dimensions and lighting conditions.
Size speakers for your room volume, plan Dolby Atmos layouts, and visualize speaker placement with our room planner.
Get equipment suggestions that match your calculated requirements, with links to purchase from trusted retailers.
All our calculators are built using established industry standards:
TheaterCalc is free to use. We earn a commission when you purchase products through our Amazon affiliate links. This doesn't affect your price - you pay the same whether you click through our site or go directly to Amazon.
We only recommend products we believe match your calculated requirements. Our calculators give you the same results whether or not a commission is involved.
